Abstract: A body-worn hub may detect that a first battery charge level of a first battery in a body-worn device connected to the body-worn hub via a wired connection is at or below a first battery charge level threshold. Accordingly, the body-worn hub may route power from the body-worn hub to the body-worn device via the wired connection to charge the first battery when a second battery charge level of a second battery in the body-worn hub is above a second battery charge level threshold. However, in response to the first battery of the body-worn device being charged to a third battery charge level that is above the first battery charge level threshold or the second battery charge level dropping to the second battery charge level threshold, the body-worn hub may stop routing power to the body-worn device via the wired connection.

The analog timing offset removal circuit removes the time offset between the analog I and Q signals. The first and second pulse shapers receive the analog I and Q signals, respectively, and output pulse-shaped I and Q signals. The adder receives the pulse-shaped I and Q signals and outputs an intermediate frequency signal.
